3 Introduction PILOT presentation The PILOT monitoring device allows the change in the circuit breaker s condition to be assessed in order to ensure that the network protection system works correctly. Introduction Fitted in an Evolis 24 kv circuit breaker, PILOT connects directly to the control mechanisms to enable: b verification of circuit breaker operating conditions: auxiliary voltage level, ambient temperature, number of switching operations and time between two operations, b recording of circuit breaker operating parameters. This data will be used by specialists to make a diagnosis of the circuit breaker s mechanical condition. Recorded data can be collected from PILOT either locally, or remotely via a local network or possibly via the Web using a concentrator. PE55600 PILOT functions Monitoring of circuit breaker operating conditions b The device permanently monitors: v opening coil voltage, v circuit breaker ambient temperature, v number of switching operations, v time between 2 switching operations and gives an alarm in the case of measured values exceeding the set points. b Operating conditions are dated and recorded every 24 hours: v minimum and maximum values of the monitored voltage, v minimum and maximum values of ambient temperature. The maintenance service will therefore be able to monitor the circuit breaker s environment over time (PILOT has a capacity of 1000 recordings). b The alarms are visible on the device s front face or can be consulted on a remote display. Monitoring of circuit breaker behaviour b PILOT records the last 1000 events concerning the circuit breaker: opening, closing, motor arming. PILOT energizing, exceeding an auxiliary voltage set point, exceeding an ambient temperature set point, exceeding the number of switching operatings, exceeding the time between two switching operations. b The recorded data can be given to a circuit breaker expert in order to make a diagnosis of the circuit breaker s mechanical condition. Maintenance notepad PILOT provides maintenance services with a maintenance log zone enabling information on circuit breaker operation to be recorded: 250 notes of 250 characters are available. Local front-face indication The unit s status and detected alarms are indicated on the device s front face using LEDs. PILOT parameter setting and operating software PC-based software gives access to configuration data, data recorded by the unit and data input on the notepad. This data can be accessed when a PC is connected to the PILOT unit: b either directly to the front face, b or via a remote connecting kit in the LV control box of the cubicle in which the circuit breaker is installed, an arrangement that gives access to PILOT data when the circuit breaker is not accessible. Data is presented on standard Internet Explorer software. Communication interface The PILOT device can be connected to a Modbus communication network via a connecting kit. All of the circuit breaker s monitoring data, available in the PILOT device, can then be used remotely via a supervisor. 2

7 Detailed description of functions Monitoring operating conditions 0 Auxiliary voltage Why monitor the voltage? Circuit breaker operation is guaranteed when all of the auxiliary voltages are within the authorized limits. Should these limits be exceeded, the switching time may become abnormally long and the circuit breaker s operation may be deteriorated. A voltage level outside of the limits can be a sign of a fault in charge level of the batteries, in which case maintenance operations will be necessary. The auxiliary voltage used for opening is constantly monitored to guarantee the circuit breaker s key functions. Monitoring principles PILOT is supplied power via the energy source used for circuit breaker opening. PILOT permanently samples the supply voltage and, after filtering, compares it with the monitoring set point. DE x% +10% type U (V) Set point definition By default, PILOT indicates any exceeding of values relative to the standardized coil operating range (of 30% to +10% of the rated dc voltage level or 15% to +10% of the rated ac voltage level) guaranteed by Schneider Electric. However, it is possible to modify the minimum and maximum thresholds by a correction factor (+x%, y% of the rated voltage) in order to extend the monitoring range. 30% y% t (s) The set point then becomes: 30% x% to +10% +y%. The values x and y are input when setting parameters in PILOT using setup/ installation parameters in the PILOT software. Monitoring auxiliary voltage Light gray zone: auxiliary voltage within the standardized operating range of the coil. Dark gray zone: auxiliary voltage in an extended operating range for the coil. Beyond that: auxiliary voltage outside of the coil s operating range V alarm. Voltage Coil type Rating Tolerance Umin Umax Direct 24 V V 30% +10% V 48 V V 30% +10% V 100 V V 30% +10% V 200 V V 30% +10% V Alternating 100 V V 15% +10% V 200 V V 15% +10% V 6

8 Detailed description of functions Monitoring operating conditions Ambient temperature Why monitor the temperature? Circuit breaker operation is guaranteed when the ambient temperature is within the authorized limits. Beyond the maximum temperature, the circuit breaker must be operated at lower current levels than its maximum performance levels. Near to the minimum temperature, the mechanisms require closer monitoring. The PILOT device permanently monitors the circuit breaker s ambient operating temperature and indicates any exceeding of the set points. Monitoring principle A sensor permanently measures the temperature inside the device. Corrections are provided to take account of self-heating inside the casing and the device in order to give the ambient temperature around the circuit breaker. PILOT compares the measured values with the upper and lower set points of the authorized values. However PILOT does not take account of circuit breaker heating which is dependent on the installation architecture (cubicle type) and operation. Set point definition The maximum permissible upper temperature set point is defined by the position of the switch on the front face of the device. Four threshold values are available: 40 C, 45 C, 50 C and 55 C. The lower minimum admissible temperature set point is defined by the value given when setting parameters using the device s PILOT software in setup/warning parameters. The possible setting ranges from 25 C to +5 C in increments of 1 C 7

9 Detailed description of functions Monitoring operating conditions Number of switching operations Why monitor the number of switching operations? Circuit breaker operation is guaranteed for a maximum number of operations. Whilst exceeding this value can be tolerated, it requires closer monitoring of the device. The PILOT device permanently monitors the number of circuit breaker switching operations and indicates when the set point is exceeded. Monitoring principle The switching operation counter is incremented every time the circuit breaker is electrically closed in the same way as the circuit breaker mechanical counter. However, manual switching operations of the circuit breaker will not be taken into account. When the device is installed, the electronic counter must be set to the same value as the mechanical counter. Set point definition The set point for the maximum permissible number of switching operations is defined by the value input when setting the device s parameters in the Setup/warning parameters part of the PILOT software. 8

10 Detailed description of functions Monitoring operating conditions Maximum time between switching operations Why monitor the time between 2 switching operations? If the circuit breaker is not switched for a long period of time, this can cause it to malfunction (seizing of mechanisms). Exceeding of this value requires closer monitoring of the device. It is recommended to operate the device once a year. The PILOT device permanently monitors the time between 2 switching operations and warns if a value is exceeded. The time is expressed in days. Monitoring principle The switching counter is incremented every time the circuit breaker is electrically closed. This switching operation is dated, the device permanently calculates the time since the last operation and compares it with the set point. When the device is de-energized, the calendar circuit is supplied power from the lithium back-up battery. When re-energized the device updates the time since the last switching operation. d Please note: manual switching operation does not increment the counter and does not re-set the time counter, it is therefore recommended to carry out an electrically controlled operation. Set point definition The set point for the maximum time between 2 switching operations is defined by the value input when setting parameters for the device in Setup/ warning parameters in the PILOT software. 9

11 Detailed description of functions Monitoring operating conditions Recording of usage conditions Introduction PILOT records the daily minimum and maximum values of the voltage supplying the opening coil together with minimum and maximum values of ambient temperature. Characteristics of the usage conditions buffer The daily values of usage conditions are stored in a rotating buffer of 1000 lines (only the last 1000 events are saved). Each event line comprises 5 fields: Date θ min. θ max. Vaux min. Vaux max. 06/03/ /03/ /03/ /03/ /03/ /03/ /02/ /02/ /02/ Date Calendar date saved on the day of the recording. θ min.

Maximum auxiliary opening voltage sampled during the day. 10

12 Detailed description of functions Notepad 0 Introduction To facilitate monitoring of circuit breaker maintenance, the PILOT device provides maintenance services with a maintenance log book using a notepad feature. 250 notes are available in the device. The actual number of notes used is given in the number of notes field. The notepad can be accessed via the PILOT software. Notepad characteristics The notepad has zones of free text. The last recorded note or the last modified note is always the first note to be visualized. PE

13 Detailed description of functions Monitoring circuit breaker behaviour Event log Introduction A circuit breaker s behaviour can be characterized by the change in the time it takes to open, close and arm the motor. PILOT records these operating parameters, measured on each switching operation. This data provides a historical log of the circuit breaker switching operation. To supplement these measurements, PILOT also records: b the energizing of the device, b alarms given from monitoring operations (auxiliary voltage, ambient temperature, switching operating counter, time between 2 switching operations). Characteristics of the events buffer Events are stored in a rotating buffer of 1000 lines (only the 1000 last events are saved). Each event line comprises 8 fields: CPT Type Vaux Time θ Date Hour State 2000 Overflow cpt /01/ Overflow cpt Open ms 24 10/01/ Normal 95 Close ms 24 10/01/ Normal 95 Motor s 24 10/01/ Normal 95 Restart /01/ Normal 95 Voltage /01/ Voltage 95 Temperature /01/ Temperature 95 Overflow time /01/ Overflow time CPT: counter value managed by the device Type: event type b Open: opening operation b Close: closing operation b Motor: mechanism arming b Restart: device energizing b Voltage: auxiliary voltage overflow alarm b Temperature: temperature overflow alarm b Overflow cpt: switching counter overflow alarm b Overflow time: time between 2 switching operations overflow alarm Vaux: value of measured voltage as a function of event type Time: switching operation duration measured as a function of the event type (opening, closing, motor arming) θ: ambient temperature Date: event date Hour: event time.

DE55538 Motor cycle Voltage present across the closing coil terminals Circuit breaker position input: 1 = open 0 = closed Voltage present across the arming motor terminals Motor arming When the circuit breaker has completed its closing cycle, it rearms the mechanism using the rearming motor. This motor is activated as soon as the circuit breaker is switched to the closed position right through to the appearance of the end of arming contact which breaks the power supply to the motor. Through the NC and measurement inputs, the device: b triggers the timer, b measures the value of voltage applied across the motor terminals, Through its measurement input, the device: b detects the disappearance of voltage and stops the timer. Arming time 13

15 Detailed description of functions Monitoring circuit breaker behaviour Event log Energizing Every time the PILOT device is re-energized, it records the fact that it has been reset and notes the sampled ambient temperature, the date and the time as well as the device status. Auxiliary voltage alarm The appearance of an auxiliary voltage alarm causes the device to record its fault status and notes the fault voltage, the sampled ambient temperature, the date and the time as well as the device status. Ambient temperature alarm The appearance of a temperature alarm causes the device to record its fault status, noting the fault temperature. Alarm for exceeding the authorized number of switching operations The appearance of an alarm for exceeding the authorized number of switching operations causes the device to record its fault status and note the value of the switching operation counter, the sampled ambient temperature, the date and the time as well as the device s status. Alarm for exceeding the time between 2 switching operations The appearance of an alarm for the time between 2 switching operations causes the device to record its fault status, noting the value of the switching operation counter, the sampled ambient temperature, the date and the time as well as the device status. The time calculated by the device can be seen in Actual values in the PILOT software. 14

36 Modbus communication Presentation 0 General Modbus communication allows the PILOT device to be connected to a supervisor or to any other piece of equipment with a Modbus maters communication channel. PILOT is always a slave station and must be connected to the communication network via one of the Sepam range communication interfaces Sepam: b ACE949-2: RS wire link, b ACE959: RS wire link, b ACE937: optical link. Accessible data The data that can be accessed from the RS 485 Modbus link include all of the data managed by the device, accessible via the PILOT software. Parameter setting data b Circuit Breaker Characteristics b Configuration parameters b Communication parameters b Installation parameters b Warning parameters b Initial measurements Monitoring data b Actual values b Events b Condition line records Maintenance data b Maintenance bloc-notes Access procedures According to the data, two different access procedures can be used: b direct access: the data is directly accessible in one reading or writing transaction, b indirect access: access to the data requires several reading transactions. This access is dedicated to read records: Events, Condition line records and Maintenance bloc-notes. Please, read each line of the data. Example: to read five lines of event records, you have to read data at addresses: 1000, 1001, 1002, 1003,

37 Modbus communication Modbus protocol management 0 Protocol principle Modbus allows the exchange of data between a master device and one of several slave devices, identified by a number. It is based on a request-response type dialogue, the request always being sent by the master. Modbus exists in ASCII or binary form (RTU mode). The data exchanged is of 16 bit type (still called registeror of single bit type. Each piece of data (bit or register) is identified in the device by a 16 bit coded address. The detailed protocol description can be obtained on the internet site: Supported Modbus functions The Modbus protocol in PILOT devices is a sub-assembly that is compatible with the Modbus RTU protocol. The following functions are processed by PILOT: b function 3: reading n output or internal words, b function 4: reading n input words, b function 6: writing 1 word, b function 8: reading Modbus diagnosis counters, b function 16: writing n words. The supported exception codes are: b 1: unknown function code, b 2: incorrect address, b 3: incorrect data, b 7: non acquittal (tele-writing and tele-setting). Multi-master operation When PILOT devices are connected via a gateway to a network authorizing multiple access (Ethernet, Modbus+, etc.), several master units are likely to address the same PILOT on the same communication port. The Modbus series protocol does not manage this type of architecture. The solving of any possible conflicts is the responsibility of the network designer. b For directly accessed data, no precaution is generally required. b For indirectly accessed, PILOT offers two exchange zones on each port allowing two simultaneous and independent access procedures by two different master devices. Performance levels The return time (the time between the end of reception of a request and supplying of the response) is typically less than 10 ms for 90% of exchanges. Sometimes it may be higher, without being more than 150 ms. In indirect mode, the time required between a request (or clearing) and the availability of the corresponding data is related to PILOT s non priority cycle time and can vary from a few tens to a few hundreds of ms. 36

38 Modbus communication Implementation 0 Installing the communication network Preliminary study The communication network must be subject to a preliminary technical study which will determine the following according to the installation characteristics and constraints (geography, quantity of data processed, etc.): b the type of media (electrical or optical), b the number of PILOT devices (or slaves) per network, b the transmission speed, b the configuration of ACE interfaces, b parameter setting of the PILOT device. Transmission characteristics Transmission type Character format Communication speed Asynchronous series 8 data bits 1 stop bit Parity according to parameter setting 4800, 9600, 19200, baud Characteristics of RS 485 electrical interfaces Electrical interface ACE949-2 Conformity with EIA standard ACE959 Differential RS wire In conformity with EIA standard Differential RS wire Power supply of electrical interfaces Connection type Maximum number of PILOT devices on a network Per external auxiliary supply 12 Vdc or 24 Vdc Screw terminals and tightening clamps for shielding 25 Maximum length of the RS 485 network with standard cable Number of PILOT devices 12 Vdc supply 24 Vdc supply m 1000 m m 750 m m 450 m m 375 m N.B.: links multiplied by 3 with a high performance FILECA F cable (maximum 1300 m).

39 Modbus communication Implementation Installing the communication network Setting the communication parameters Commissioning of the communication option requires preliminary setting of several parameters using the PILOT software. These parameters are saved in the case of power outage. Communication parameters Factory setting Protocol type Without, Modbus, CAN If Modbus choice No. of slave units 1 to 255 Transmission speed 1200, 2400, 4800, 9600, or baud Parity Even, odd, without parity The allocation of the Modbus slave number must be carried out before connecting the PILOT to the communication network. It is also very advisable to set the other physical communication parameters (speed, parity) before connecting to the communication network. Modification of the communication parameters in normal operation does not disturb PILOT. The new parameters will be taken account of the next time the device is energized. 38

40 Modbus communication Implementation Connection test network Line activity indicator light The green indicator light on ACE949-2, ACE959 or ACE937 accessories is activated by variations in signal on the Modbus network. When the supervisor communicates with PILOT (either sending or receiving), this green indicator light will flash. After cabling, check that an indicator is given by the indicator light when the supervisor works. Please note: flashing indicates the flow of data to or from PILOT, it does not mean that the exchange is correct. Diagnosis counters Counter definition PILOT manages Modbus diagnosis counters. These are: b CPT1: number of correct frames received, whether the slave is concerned or not b CPT2: number of frames received with CRC error or physical error (frames comprising more than 255 bytes, frames received with at least one parity error or overrun or framing, break on the line). b CPT3: number of exception responses generated (even if not sent, due to a broadcast request being received) b CPT4: number of frames specifically addressed to the unit (apart from broadcast) b CPT5: number of broadcast frames received without error b CPT6: not significant b CPT7: not significant b CPT8: number of frames received with at least one character having a physical error (parity or overrun or framing, break on the line) b CPT9: number of correct requests received which are correctly executed Resetting counters The counters are reset to 0: b when they achieve the maximum value FFFFh (65535) b when they are reset to zero by a Modbus command (function 8) b when the auxiliary power supply is stopped to PILOT b when the communication parameters are modified. Use of counters Modbus diagnostic counters help detect and resolve communication problems. They are accessible via dedicated reading functions (functions 8 and 11 in the Modbus protocol). An erroneous speed (or parity) causes an incrementation of CPT2. A lack of reception is observed in the non-change in CPT9. Operating anomalies It is recommended to connect PILOT devices one by one on the Modbus network. Make sure that the supervisor sends frames to the PILOT concerned by checking the activity in the RS RS 485 or optical converter if there is one, and with the ACE949-2, ACE959 or ACE937 device. RS 485 network b Check the cabling to each ACE device b Check the tightening of the screw terminals on each device b Check connection of cable CCA612 connecting the ACE949-2 or ACE959 to the PILOT unit. b Check the polarization which must be single and the adaptors which must be placed at the ends of the RS 485 network. b Check that the cable used is the recommended type b Check that the ACE909-2 or ACE919 converter that this used is correctly connected, powered and set. Optical network b Check the connections to the ACE device b Check the connection of the CCA612 cable linking the ACE937 device to the PILOT unit. b Check that the converter or the optical star is correctly used, connected, powered and set. In all cases Check the slave number, the speed, the format with the PILOT software. 39
